SPRING BED-BOTTOM.

Specification of Letters Patent.

Patented Jan. 9, 1917.

Application filed February 16, 1915. Serial No. 8,470.

To all whom it may concern Be it known that I, MAYER DAXE, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Spring Bed-Bottoms, of which the following is a specification.

' My improvements relate to means for supporting spring bed bottoms on bedsteads.

Heretofore the elastic resilient mattress support constituting the bed bottom has been permanently attached to a rigid rectangular frame so that the spring bottom could only be placed upon or removed from the bedstead by lifting it and its supporting frame bodily;'and as the frame was necessarily heavy in order to afford the requisite degree of strength to hold the spring bottom extended and taut the services of two persons has been necessary in order to properly handle the spring bottom and its frame. Furthermore the rigid structure and size of the bed bottom frame was av disadvantage in that it was not only difficult to handle, but took up much space, and was not adapted to convenient transportation or manipulation for purposes of cleaning, &c., and added materially to the cost of the bed bottom as well as to its weight and cumbrousness.

These objections I obviate by my invention which is designed to afford a light weight elastic resilient bed bottom which may be detachably secured directly to the bedstead and expeditiously applied or removed therefrom, and which when detached may be rolled up for transportation or storage, or

' conveniently manipulated for purposes of cleaning, &c. Andall this may be accomplished by one person alone.

The invention consists in the combination, construction and arrangement of parts herein described and claimed specifically, distinctive features being the dispensing with the sidemembers of the spring bottom frame, or more correctly with any frame therefor at all,the elastic resilient support for the mattress being attached sim-.

ply to end bars'or rods; and the provision of means whereby said elastic resilient mattress support may be detachably secured to the end cross bars of the bedstead frame, all as hereinafter more fully set forth.

In the accompanying drawings, Figure 1, is a top view, more or less diagrammatic, representing the practical application of my invention; Fig. 2, is a sectional elevation upon a larger scale showing the structure and illustrating the operation of one of my bed bottom tightening and securing devices 3 Fig. 3, atop view of the parts shown in Fig. 2; Fig. 4, asectional elevation in detail ofone of the bed bottom end holders; Fig. 5, a top view of the parts shown in Fig. 4; Fig. 6, is adetail view of a portion of one of the end cross bars of the bed bottom.

F, represents a bed frame of any ordinary or desired construction, of which f, 7, are the corner posts, f, f, the end cross bars or members extending between and attached to said posts, and f F, the longitudinal members of the frame also connecting said end posts 7, f. The end cross bars are usually rectangular in cross section and I have herein shown and described them as of angle iron structure, although this is not an absolutely essential feature since other forms in cross section of the end. frame bars f, 7, may be utilized for my purpose.

My bed bottom B, consists of the spread or mattress-supporting surface 6, attached at its cross edges to the intermediate plates or bars 6, b, and the tension springs 6 b and end cross bars 6 Z2 ,the tension springs 6 22 being interposedbetween and attached to the intermediate bars 5, b, and the end cross bars Z2 5 The structure of the spread 79, is not material. It may be of spirally woven wire fabric or any construction found most eXpedient,-the tension springs 6 6 being relied upon, for the purposes of my invention, to afford the requisite degree of elasticity and resilience in use.

jAs before mentioned the usual longitudinal members between the end cross bars 6 heretofore constituting therewith a rigid frame for the mattress support, are omitted, so that the latter when detached from the bed frame F, may be. folded or rolled up within a comparatively small compass, or conveniently manipulated for purposes of cleaning, &c. The omission of these longitudinal members of the bed bottom is an important factor in the case since it materially reduces the weight of the bed bottom and simplifies the structure as a whole, so that a single person can easily handle and manipulate the bed bottom for all practical purposes. V

In order to detach'ably connect the bed bottom B, with the bedstead frame F, I provide hook members H, preferably attached to the cross member f, at the foot ment is not material, and may be reversed if desired, asfound most convenient under the circumstances and conditions of use. These holding members H, and the tightening de vices T, may be permanently incorporated with the cross bars f, f, of the bed frame F, if desired, although in adapting. them for use on bed framesalready in existence or as ordinarily manufactured, I prefer to make both the holding and the tightening devices separate from both the bed frame and from the bed bottom. This however is a matter of choice and does not affect the operation of the parts. Again, two holders H, H, and two tightening devices T, T, may be provided, or more if found expedient in the case of wide beds. 'When detachably se-- cured to the bedstead frame, the holders H, are formed with hooks h, and the tightening devices T with hooks t, which hooks fit the under sides oredges of the end cross members f, f, of the bedstead, as shown more particularly in Figs. 2, and 4. Each holder H, is also formed with a shoulder or bearing h, to rest on the top of the cross bar 7, and with a cross head 1?, formed with a rear extension h adapted to enter a recess b formed for its'reception in an end cross member 21 of the bed bottom B, as shown more particularly in Fig. 4. In like manner the fulcrum member t, of each tightening device T, rests upon the top of its bed frame end cross member 7; and the hook end 6 of its tightening lever 15 is adapted to enter a slot or recess 72*, formed for its reception in said end cross member 6 of the bed bottom as'shown clearly in Fig. 2, of the drawings. Each tightening lever 25 is pivotally connected, as at t, Figs. 2, and 3, to the fulcrum member 25, the inner end If, being used as a handle; Attached to the fulcrum member t, is a spring latch 6 for engagement with a shoulder on the end of the hook arm for the purpose of holding the tightening lever ,15 if, in its depressed position, as shown in solid lines in Fig. 2, the other or raised position being shown therein in dotted lines.

The operation will be readily understood.

7 The holdingdevices H, and tightening devices T, being in position on the end cross members f, of the bedstead, Whether temporarily or permanently so situated, one of the bed bottom end cross bars bflis coupled to the holders H, by passing the ends 72. of the latter through the recesses bfl'in the cross bars, as illustrated in Fig.- 4. At the other end of the bedstead, each'tightening lever t being elevated into approximately the position shown in dotted lines in Fig. 2, the end cross bar 6 at this extremity of the bed bottom is connected with the levers t by passing the hook ends of the latter through the recesses 6 in said end cross bar 72 of the bed bottom, and then each lever 75 by means of its handle member 16 is brought into a substantially horizontal po sition as shown in solid lines in said Fig. 2, the spring latch 25, in each case locking the lever automatically. During the operation of lowering the levers t the tension springs 6 are stretched by reason of the contact of thebed bottom end cross bar 6 with the shoulder t onsaid lever t the depression of the lever being limited by contact of the stop t", with a stationary part, as for instance the fulcrum member t,thereby drawing all parts of the bed bottom taut for use. When it is desired to remove the bed bottom B, from the bedstead the latches t, are pressed back from the shoulders on the hook ends 6 of the tightening levers t when the resilience of the springs 6 will draw the levers t up again into the position indicated in dotted lines in Fig. 2, so that the end cross piece 6 of the bed bottom may be readily withdrawn from the hook ends F, of the levers 25 This obviously slackens the whole bed bottom longitudinally so that it is an easy matter to lift the other end cross bar 5 from the holders H, at the opposite end of the bedstead. Thus released, the bed bottom B, may be folded or rolled upon itself for convenience of transportation, storage or manipulation.

My improvements are of especial importance from a sanitary point of view since they render the cleansing of the bed bottom and bedstead comparativel easy operations; and as most bedstea s are sectional and can be taken apart, the invention obviously facilitates moving, transporting or storage, as there is no rigid heavy cumbersome bed bottom frame to take care of, or to monopolize space.
